Generally speaking They're 32" in diameter and the sidewall is 7.5" wide

This changes when installed !!

Just remember those are nominal size and can and will change depending on type, manufacturer and other factors (like rim width.) When in doubt, and when you need to know exactly, go to the manufacturer's website and find the tire you're interested in. Click on specs and find the size.
